A new study from the University of Southhampton finds that drinking cup of coffee every day may reduce the risk of hepatocellular cancer, the most common form of liver cancer, by a fifth.

For the study, the researchers conducted a systematic review and meta-analysis of more than 26 observational studies, including 2.25 million adults. The analysis demonstrated that drinking just one cup of coffee every day was connected to the 20% reduction of HCC, while the risk of HCC was halved when consuming up to 5 cups of caffeinated coffee on a daily basis.

Dr. Oliver Kennedy, the lead author of the study, says: “Coffee is widely believed to possess a range of health benefits, and these latest findings suggest it could have a significant effect on liver cancer risk.”
